The rapper says that he had known about his mum's sexuality for a long time

He raps about the moment on album track Smile, with the lyrics "Mama had four kids, but she's a lesbian/Had to pretend so long that she's a thespian. Had to hide in the closet, so she medicate/Society shame and the pain was too much to take."

Speaking on David Letterman’s new Netflix show, the rapper said: "I was so happy for her that she was free.”

He added: “Imagine having lived your life for someone else. And you think you're protecting your kids.

"For my mother to have to live as someone that she wasn't and hide and like, protect her kids — and didn't want to embarrass her kids... for all this time.
